Abstract (en)

[origin: US6685829B1] The invention relates to a fluid filter, such as an oil filter for a combustion engine. The inventive filter comprises an exchangeable filter inset which is provided with a ring-shaped cross-section that encompasses an inner chamber. The outlet for the purified fluid is joined to the inner chamber. The inventive filter also comprises a discharge line for emptying the filter during a filter change. A central discharge dome is provided which extends into the inner chamber. Said dome, together with the filter inset is mounted in such a way as to be axially displaced between a first closing position which closes the discharge line and a second release position which releases the discharge line. According to the invention, the discharge dome is fixed to the housing and is pushed into the release position thereof when said dome is impinged upon with a spring. The dome can be moved into the closing position thereof against the action of the spring and by means of the filter inset which is inserted into the filter housing.
